Abstract
A lock nut includes a nut body (10) having outer (12) and inner (14) circumferential surfaces. The inner surface (14) defines a screw-threaded axial through-hole that can be mounted on an externally threaded shaft. A plurality of blind bores (18) is formed in the nut body (10), each blind bore extending radially inwardly from the outer surface. Those blind bores (18) terminate short of the inner surface so that a plastically displaceable part (20) of the nut body remains between each blind bore and the inner surface to close-off a radial inner end of the blind bore (18). Locking screws (30) are mounted in respective blind bores (18). By tightening the locking screws (30), the displaceable portions (20) are pressed against the externally threaded shaft to frictionally grip the shaft.
